  Recent studies show that donor-site morbidity after harvest of a free osteocutaneous fibula segment is low. 38,39 The most frequent complaints are pain, dysesthesia, and a feeling of ankle instability. [jpma.org.pk]

The authors followed up 9 cases of congenital pseudoarthrosis associated with neurofibromatosis-1 (or Von Recklinghausen's disease) at least 2 years after the end of treatment using Ilizarov's method. [moh-it.pure.elsevier.com]

Conventional treatments used included excision of the pseudoarthrosis, correction of the deformity, intramedullary fixation, bone grafting and soft tissue transplantation for lengthening and coverage. [ncbi.nlm.nih.gov]

Prognosis continues to be reserved especially in clepsydra forms and those localised to the lower third of the tibia. [moh-it.pure.elsevier.com]

The prognosis of CPT is very much related to the radiologic classification. Crawford type 2 and Crawford type 4 pseudoarthrosis have a worse prognosis, with a lower percentage of fusion at the site of pseudoarthrosis. [ncbi.nlm.nih.gov]

Type 2 have a relative poor prognosis. Type 3 cases are usually of late onset type which develops as a stress fracture of congenital dysplastic tibia or in a healed tibia after previous bone grafting & has the best prognosis. [de.slideshare.net]

The prognosis is good if the lesion is located only on the fibula, an extension to the tibia has a prognosis similar to type II, Type VI Associated with an intraosseous fibroma or a schwannoma. [boneandspine.com]

Abstract The purpose of study was to refine frequency of etiological factors and characteristics of congenital pseudarthrosis of tibia (CPT). Materials and Methods. [journals.eco-vector.com]

Congenital pseudoarthrosis of the tibia (CPT) is an uncommon disease whose etiology and pathogenesis is unknown. [ncbi.nlm.nih.gov]

Pathology The etiology is unclear, however, around 50% of cases are associated with neurofibromatosis type 1 (NF1). Overall, 10% of patients with NF1 are diagnosed with tibial pseudoarthrosis. [radiopaedia.org]

Etiology Each type of tibial bowing tends to have its own etiology. [emedicine.medscape.com]

The etiological nature of this lesion is unclear, however there is a strong association between CPT and neurofibromatosis type I (NF-I). [jlponline.org]

The pathophysiology of the resultant limb-length inequality may be related to the bowing. [emedicine.medscape.com]

At the end of the correction, a telescopic Fassier-Duval intramedullary nail was used prophylactically to prevent re-fracture. After 2 years of follow-up, X-ray images show bone-healing without any bowing. [ncbi.nlm.nih.gov]
